Design, fabrication, and testing of a hopper-feeder-bolter

Technical Report ·
OSTI ID:6835927
This report documents the design, fabrication, testing, and coal mine demonstration of a hopper-feeder-bolter during a four-phase program. The machine was designed to increase productivity and safety in underground room-and-pillar mining. It performed well as a hopper-feeder for continuous haulage during a coal mine demonstration. Testing in a simulated mine showed that the machine also has good roof bolting capability.
